Supported Configurations
Operation of multiple switches in a fabric topology is subject to the following
topology limits. Consider the impact of these limits when planning the fabric.
Note: For more information about planning the fabric, refer to hp StorageWorks SAN
high availability planning guide.
■Fabric Elements—Each fabric element is defined by a unique domain ID that
ranges between 1 and 31; therefore, the theoretical limit of interconnected
directors in a single fabric is 31. The supported limit of interconnected
switches in a single fabric is 24. Because this number is subject to change,
contact your HP authorized service representative for the current number of
interconnected switches supported in a single fabric.
■Inhomogeneous fabric—To determine if interoperability is supported for a
product, or if restrictions apply, refer to the product publications, or contact
your HP authorized service representative.
■Number of Interswitch Links (ISLs)—Theoretically, the ISL limit per
Director 2/64 is 32 and for Director 2/140 is 70. The maximum supported
number of ISLs per director is half of the director ports. For redundancy, at

Cable Requirements
8Director Release Notes
least two ISLs should connect any two director-class fabric elements. Because
this number is subject to change, contact your HP authorized service
representative for the current number of ISLs supported per director.
■Hop Count—The fibre channel theoretical limit of ISL connections traversed
(hop count) in a single path through a fabric is 7. The maximum supported
hop count in a single path through a fabric is 3. Because this number is subject
to change, contact your HP authorized service representative for the current
hop count supported by a single fabric path.
Note: The hop count is equal to the number of ISL connections traversed in a single
path, not the total number of ISL connections between devices.
Cable Requirements
Note: Please note that optical cables for the Director 2/64 and Director 2/140 must
be ordered separately.
For cables measuring up to 500 meters (1 Gbps) or 300 meters (2 Gbps), use
multi-mode Fibre Channel cables. For longer cables, use single-mode Fibre
Channel cables.
Multi-mode optical cables are connected to short-wave optical transceiver
modules in a switch. Single-mode optical cables are connected to long-wave
optical transceiver modules in a switch. Multi-mode cables should use 50/125
optical fibers, and single-mode cables typically use 9/125 optical fibers for
distances up to 10 km.
Verify that connectors interfacing with the Director 2/64 and Director 2/140 use
LC Duplex connectors with a PC finish. In addition, the connector at the opposite
end of the cable must use either LC or SC type, depending on the requirements of
the connected device.

Important Information
9Director Release Notes
Important Information
This section describes important information related to the Director 2/64 and
Director 2/140.
HAFM Upgrade Required for Firmware Version 04.01.02 Build 04
If you are using the HAFM server to manage the Director 2/140, Director 2/64,
Edge Switch 2/32, Edge Switch 2/24, and/or Edge Switch 2/16, and they are
running firmware version 04.01.02 build 4, you need to upgrade HAFM to version
06.03.01 build 5 (minimum). For more information on upgrading software
versions, refer to the HP StorageWorks HA-Fabric Manager User Guide.The features
of this software version are detailed in the accompanying manuals.
Zoning is Disabled by Default
The default zone on the Director 2/64 and the Director 2/140 is disabled by
default. Zoning must be configured in order for any devices connected to the
director to communicate.
Known Issues
This section describes the known issues related to the Director 2/64 and
Director 2/140.
HSG80 Transparent Mode Not Supported with IBM AIX
Use of an HSG80 with IBM AIX is restricted to operating the HSG80 in Multibus
mode with the Director 2/64 and Director 2/140. Transparent mode is not
supported at this time.
Workaround
None.

Known Issues
10 Director Release Notes
HSG80 Transparent Mode Not Recommended with Controller in SCSI-3
Mode with HP-UX Operating Systems
Due to an issue with non-existent duplicate LUNs being displayed with the
HP-UX operating systems, the HSG80 controller is restricted to SCSI-2 mode of
operation when set to Transparent failover mode.
SCSI-3 mode of operation in Multibus failover mode is fully supported with the
use of Secure Path software, Version 3.0.
Workaround
None.
ISL Disconnect Causes NOS Error with the OpenVMS Operating Systems
When an ISL connection is physically removed between directors or switches, the
Fibre Channel Adapter model FCA2354 transmits a Not Operational Sequence
(NOS) error. This is observed as an entry in the HAFM server Link incident log
for the port in which the FCA2354 is attached. The director’s Hardware View also
displays a yellow triangle icon over the port that detected this incident. The fabric
operation or data movement is not disrupted by these incidents, which can be
cleared using the following procedure.
Workaround
Use these steps to clear the incident alerts.
1. At the HAFM Hardware View, click the port module to open the Port Card
View.
2. Right click on the port with the yellow triangle icon, and choose Clear Link
Incident Alert(s).
Disconnecting the Null Modem Cable
Always log out and disconnect the Null Modem cable from the serial maintenance
port when not in use or when the switch is reset.
Using the Same Firmware
All switches and directors managed by HAFM should have the same FW level
installed—whether 1 Gbps or 2 Gbps capable.

Known Issues
11Director Release Notes
Reinstalling Feature Licenses
Feature Licenses (or keys) must be reinstalled after performing a factory reset on a
director to regain use of the licensed features (e.g., SANtegrity).
Multiple FC HBA Ports in Separate Zones
Multiple FC HBA ports in the same host should be placed in separate zones, or
they might be perceived as potential targets (some HBAs log-in as both host and
target).
CTP Controls Port Lights
Port lights on the edge switch and director products are controlled by the CTP
functionality. Certain activities such as FW updates, IPLing the CTP, or switching
over to the backup CTP (Director) can cause these port lights to extinguish
momentarily until control is reasserted by the CTP. The actual FC traffic is not
affected during these times.
Support for Speed Auto-Negotiate
Currently, Speed Auto-Negotiate is not supported for HA and Failover SAN
configurations and is not recommended in general at this time. The speed should
be hard set to match the attached host or target port capability whenever possible.
Hot Insertion of an Optical Transceiver May Produce Port Failure Event
There should be no impact to the switching and throughput capabilities of the
director and the error event can be cleared by performing a Port Reset.
Ports May Accumulate Spurious Events
A port may accumulate “Invalid transmission word” and “Bit-Error Threshold
Link Incident” events when a transceiver is poorly seated resulting in a poor
ground connection.
Workaround
Reseating the optical transceiver will correct the problem.

Known Issues
12 Director Release Notes
Director Properties Description May Be Incorrect
The text shown in the Description field of the Director Properties panel for the
Director 2/140 may be incorrect. It may show SAN Director 64. This has no
effect on the operation of the Director 2/140. This is a user-configurable
description for the director, and may be changed to whatever you want by
choosing Configure > Identification using HAFM, or by choosing Configure >
Director > Identification using the Embedded Web Server interface.
IML Is Required After Performing a Configuration Reset
If a Reset Configuration is performed on a Director 2/140 to reset the director to
factory configuration, an initial machine load (IML) is required to be performed to
complete the process. This is done by pressing the white button on the front of
either CTP card for more than three seconds. This can also be accomplished by
turning the power to the Director 2/140 off, and then back on.
HP-UX - Potential Conflict Between Command View and ioscan
There is an issue involving a conflict between the Command View host agent and
the UNIX command ioscan. When this conflict is encountered, ioscan may
erroneously report that storage LUNs have been lost (ioscan output results in
report of “NO_HW”). There is no actual impact on any of the servers, storage, or
any fibre channel data transfers. When encountered, re-running ioscan after a
short time will yield correct results.
The OpenView Storage Area Manager (OVSAM) Command View Host agent on
HP-UX has a discovery agent (diald) which periodically checks the system for
new I/O devices including HBAs. The default polling cycle is 19 minutes but is
user configurable from 1 minute to 24 hours. The Command View products use
this host agent component for discovery of XP and VA arrays.

Known Issues
13Director Release Notes
Workaround
On a stable system after the diald software has run for a few cycles the discovery
information will remain unchanged. In order to minimize the opportunity for this
conflict to occur with any programs using ioscan, you can modify the polling
period to a larger value. To do this, the entry
“DIAL_DISCOVERY_DELAY”
in the file
/opt/sanmgr/hostagent/config/dial.cfg
should be changed. The polling period value should be specified in minutes, e.g. a
value of 60 would result in a 1 hour discovery poll cycle. The polling period value
should be modified considering the time and frequency that ioscans are being run,
in order to avoid diald and ioscan being executed simultaneously.
This issue will be corrected in the next release of director and edge switch
firmware.
